To llwhmnztmagi/ concern# Be it known that 'L TRACY Re CAMPBELL, a citizen of the United States of America, and resident of Uutremont, city 6 of Montreal, in the Province of Quebec and Dominion of Canada, have invented certain new land useful Improvements in Loose- Leaf indem, of which the following is a specification.,

rllhis invention relates to improvements in loose leaf binders, of the type having a retaining member formed with posts designed to extend through suitable perforations in the loose leaves and by which they .i are locked in position, and the objects of the invention .are to provide simple and edective means for positioning the loose leaves and retaining them in proper alignment, and generally to improve an 2o simplify the construction of the device and better adapt the various parts to perform the functions required of them. i

3 lt consists essentially of the improved construction hereinafter described in detail in the accompanying specification and drawinl 1 1.. the drawlngs: Figure 1 is a perspective view of an embodimentof the invention to Figure 1a is a detail, showing a portion of one of the loose leaf sheets.

Figure 2 is a perspective detail of the supporting member. Figure 3 is a perspective detail of the reso taining member.

Figure t is an end view. Figure 5 is a sectional elevation taken through the binding posts.

Figure 6 is a section on the line m-w, Fi re 5.'

igure 7 is a sectional elevation of the retaining member.

Figure 8 is a perspective view of the lock in member.

dn the drawings, like characters of reference indicate corresponding parts in all the res.

Re err'ing to the drawings; 10 and 11 indicate xed binding posts deto sied to extend through open slots 12 in the edge of each loose leaf sheet 13, each loose leaf sheet being provided with a plurality of open slots 12 to receive the hired posts and a plurality of closed slots or perforations 14 to receive the temporary posts 15 whereby, when the temporary posts are removed, the sheets will be free and may individually be adjusted, removed or replaced, or new sheets added.

lin the embodiment illustrated, two per. marient posts are' provided and three temporary posts, the temporary and permanent posts being arranged alternatively, and the outer and centre posts being temporary posts. All of the tem orary posts are connected together and hd in spaced parallel relation by means of a retaining member or bar to which the posts are fixed.

The xed posts 10 vand 11 are held in spaced and parallel relation by a supporting member C of channel shape, preferably formed of a single piece of metal having u per and lowerbars or flanges 16 and .17 rigldly connected to the top and bottom of the fixed posts. rllhe back portion 18-of`the supporting member C is designed to. abut and position the edge of the loose leaves 13,

and, it maybe po1nted out that, in some instances, the posts 10 and 11 might be omitted andthe loose leaf sheets positioned byan adjustment against the back portion 18 of the supporting member C. The temporary posts 15 are designed to extend through suitable perforations 19 in the bars 16 and 17 r)Phe retaining member B is designed to be held in engage position by spring released retaining means; the spring releasing means which l have designed comprising a Hat spring 20 secured beneath the member B an(` centrally thereof, and having its outer end turned downwardly slightly and adapted to bear againstthe bar 16 whereby the spring will tend to place the supporting member a short distance above the bar 16, and the turning of the sprin about the central posts being prevents by means of rivets 21 on opposite sides of the post.

rlhe retaining member is held in engaged position by a longitudinally slidable lockloo ing. bar D having slots 22 throughfwhichl the temporary posts extend, the edge ofthe slots being adapted to engage land loclrllat notches 23 in the tem orary posts, the edge of the slots being held in engagementy with los the posts by a spring 24 extending from one lil end of the lockin bai` D to the end of the bar 16. The loc ingl bar is also formed with slots 25 throughwhich the permanent posts and 11 may extend.

rl`he locking bar D may be .retained in position against the bar 16 in any convenient way. l have shown it positioned on the underside of the bar in a channel, formed b a retaining bar 26 which is spaced a short istance from the underside of the bar 16 and suitably connected thereto. The bar D ma be formed with a slot 27 at one end throug which a connecting rivet 28 between the bars 16 and 26 may extend. The end of the locking bar D is preferably formed with a downwardlyturned prcection 29 by means of which it may be rea ily engaged.

The supporting member. C is preferably incorporated as part of a book, the back 30 of the book being connected to the back 18 of the supporting member, and the'covers 31 and 32 bein designed to lie parallel with the. bars 16 and 17. The cover 32 is formed with a exible portion 33 designed to extend over the retaining member B whereby there will be no terior of the boo lt will be 'seen from thel foregoing that,

when the parts are assembled as shown inv 'Figure lthe retaining member B may be released y longitudinal movement of the v v bar D; upon being released will spring upwardly by action of the spring 20, when it may be grasped and` remove en removed, the sheets 13 will all be tree, and may be adjusted, removed, or added to, itV desired.l To lock the sheets in positin, the retaining member is returned to position, the lower ends of the temporary posts being pointed to facilitate their insertion, and the lockingbar Dsplringin into locking position as soon as t e notc es 23 pass beneath the bar 16.

As many'changes could be madein the above construction and. many apparently widely dijerent embodiments of my inven tion within the scope of the claims, constructed without departing from the spirit or scope thereof, it 1s intended that all matl ter contained in the accom anying specification and drawings shall e interpreted as illustrative and'not in a limiting sense.
